Life learned early on to recognize itself.

All I ask is that we compare human consciousness with spirochete ecology.

The idea that we are "stewards of the earth" is another symptom of human arrogance. Imagine yourself with the task of overseeing your body's physical processes. Do you understand the way it works well enough to keep all its systems in operation? Can you make your kidneys function? Can you control the removal of waste? Are you conscious of the blood flow through your arteries, or the fact that you are losing a hundred thousand skin cells a minute?

People think the earth is going to die and they have to save it. Thats ridiculous. If you rid the earth of flowering plants, people would die, period. But the earth was without flowering plants for almost all of its history.

All scientists agree that evolution has occurred-that all life comes from a common ancestry, that there has been extinction, and that new taxa, new biological groups, have arisen. The question is, is natural selection enough to explain evolution? Is it the driver of evolution?

I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed it until I looked for evidence.

To romp along the connected rooftops and fire escapes of Chicagos second city of garages was my young lifes passion.
